A fairly recent addition to London’s skyline and mile-high dining scene, this space at the top of the 20 Fenchurch Building (whose curved structure became infamous for reflecting the sun and melting the dashboards of nearby cars) scores top marks for the multileveled garden which gives it its name. While the Fenchurch Restaurant is the place to go for dinner, we like early starts at the Darwin Brasserie, where you can graze on a range of healthy breakfasts accompanied by a strong cup of coffee and a commanding view of London.
